  2. Unité d'environnement extérieur selon la revendication 1, dans lequel, dans le boîtier d'unité d'environnement extérieur, le ventilateur de refroidissement (40) est disposé sur le côté supérieur du condenseur à refroidissement à air (30), la première zone (90) correspond à la zone supérieure du condenseur à refroidissement à air (30), et la seconde zone (92) correspond à la zone inférieure du condenseur à refroidissement à air (30).
  3. Unité d'environnement extérieur selon la revendication 1, dans lequel, dans le boîtier d'unité d'environnement extérieur, le ventilateur de refroidissement (40) est disposé sur le côté inférieur du condenseur à refroidissement à air (30), la première zone correspond à la zone inférieure du condenseur à refroidissement à air (30), et la seconde zone correspond à la zone supérieure du condenseur à refroidissement à air (30).
  4. Unité d'environnement extérieur selon la revendication 1, dans lequel, dans le boîtier d'unité d'environnement extérieur, le ventilateur de refroidissement (40) est disposé sur le côté droit/gauche du condenseur à refroidissement à air, la première zone correspond à la zone relativement adjacente au ventilateur de refroidissement, et la seconde zone correspond à la zone relativement éloignée du ventilateur de refroidissement (40).
  5. Unité d'environnement extérieur selon la revendication 1, dans lequel trois jeux de condenseurs avec la même norme composent la première zone, et deux jeux de condenseurs avec la même norme composent la seconde zone.
  6. Unité d'environnement extérieur selon la revendication 1, dans lequel deux jeux de condenseurs avec la même norme composent la première zone, et un jeu de condenseurs avec la même norme compose la seconde zone.
  7. Unité d'environnement extérieur selon une quelconque des revendications 1 à 6, dans lequel le boîtier d'unité d'environnement extérieur comprend en outre un élément de formation de passage (12a, 12b, 34a, 34b, 32a, 32b, 32c) entre le boîtier d'unité d'environnement extérieur et le condenseur à refroidissement à air (30), pour empêcher l'air d'environnement extérieur aspiré à partir de la partie extérieure du bâtiment à travers l'unité de surface avant (60) d'être aspiré dans le ventilateur de refroidissement (40) sans passer à travers le condenseur à refroidissement à air (30).
